Descriptions:
Charge module- Linear charging.
Current- 1A adjustable.
Charge precision- 1.5%.
Input voltage- 4.5V-5.5V.
Full charge voltage- 4.2V.
Led indicator- red is charging Green is full charged.
Input interface- micro USB.
Work temperature- -10℃ to +85℃.

NOTES:
- Ampere meter can only be connected to 5v input end of the module.
- It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 is enough.
- The connection wire should not be too thick.
- .Make sure the connect point is good.
- If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-substract the charging current to avoid burn damage to chip.
- NO Reveral polarity
Package Included:
1 x 5V Micro USB 1A 18650 Lithium Battery Charging Board
